CROSS-REFERENCE TO RELATED APPLICATION

This application is a continuation application of International Application No. PCT/CN2016/106998, filed on Nov. 23, 2016, the entire contents of which are incorporated herein by reference.

TECHNICAL FIELD

The present disclosure relates to the technology field of unmanned vehicles and, more particularly, to a method for controlling an unmanned aircraft, a server, and a remote control device.

BACKGROUND

Unmanned aerial vehicles (“UAVs”) have been widely used in industries such as agriculture, forest, etc., to perform various tasks. UAVs have been proven to increase work efficiency, reduce cost, and improve safety. It is expected that UAVs will be deployed in more and more applications in the future, and UAV technologies will be further advanced.

In current technologies, the actual operator of a UAV in performing a task may not be the owner of the UAV. For example, after a customer purchases the UAV, the customer may lease or rent the UAV to other people. In some cases, the customer may authorize a company's UAV operator to operate the UAV to accomplish certain tasks. In performing a task, the UAV may be controlled by a remote control device operated by an operator. The owner of the UAV often does not have direct control of the flight of the UAV. In certain situations, when the actual operator has unreasonable behavior, or when the lease expires, the owner of the UAV cannot have the actual control of the UAV in time, which causes much inconvenience to the owner.

SUMMARY

In accordance with an aspect of the present disclosure, there is provided a method for controlling an unmanned aerial vehicle (“UAV”). The method includes receiving locking instruction information from a user terminal for locking the UAV. The method also includes transmitting a locking command to a remote control device of the UAV based on the locking instruction information, to instruct the remote control device to lock the UAV based on the locking command.

In accordance with another aspect of the present disclosure, there is also provided a server. The server includes a locking instruction receiver configured to receive locking instruction information from a user terminal for locking an unmanned aerial vehicle (“UAV”). The server also includes a locking command transmitter configured to transmit a locking command to a remote control device of the UAV based on the locking instruction information, to enable the remote control device to lock the UAV based on the locking command.

In accordance with another aspect of the present disclosure, there is also provided a remote control device for an unmanned aerial vehicle (“UAV”). The remote control device includes a locking command receiver configured to receive a locking command transmitted by a server. The remote control device also includes a locking device configured to lock the UAV based on the locking command.

The present disclosure provides a method for controlling a UAV, a server, and a remote control device. The UAV control method may include receiving locking instruction information from a user terminal for locking the UAV. The method may include transmitting a locking command to the remote control device of the UAV based on the locking instruction information, such that the remote control device may lock the UAV based on the locking command. As such, the owner of the UAV may take over the control of the UAV in time when the lease is about to expire (or has expired) or the operator of the UAV has some unreasonable behavior. This can avoid continued operation of the UAV by the lease or the operator. As such, the control of the UAV becomes flexible, which provides convenience to the owner.

In farming applications, UAVs may be used to monitor the environment in which the animals are raised and the growth of the animals, thereby realizing fine feeding, disease alarm, and scientific breeding. As a result, the production efficiency is enhanced, and the risk associated with raising animals is reduced. In finishing industry, UAVs may be used to monitor, in real time, the environment in the water body, and to precisely and automatically drop food, thereby increasing the aquatic farming efficiency.

In some embodiments, the present disclosure provides a method for controlling a UAV. FIG. 1 is a flow chart illustrating a method for controlling a UAV. The method may include:

Step 101: receiving locking instruction information transmitted by a user terminal for locking the UAV.

FIG. 2 is a schematic illustration of an application scene of the method for controlling the UAV. As shown in FIG. 2, in the entire process of controlling the UAV, various devices and systems may be involved, such as a server, a user terminal, a remote control device, and a UAV.

In some embodiments, the user terminal may be controlled by a user. The user may input locking instruction information through the user terminal. Unless otherwise noted, in the present disclosure, the user refers to the owner, manager, or lessor of the UAV. The user terminal may be a cell phone, a tablet, a computer, a digital broadcasting terminal, a message receiving/transmitting device, a game control console, a personal digital assistant, etc.

In some embodiments, the remote control device may be controlled by an operator. The operator may control the takeoff, task performing, or landing of the UAV through a suitable input device, such as a key, a button, a joystick, a touch screen, etc. While performing the task, the UAV may send data back to the remote control device.

In some embodiments, the entity for performing the disclosed methods may be a server. The server may communicate with a user through the user terminal. In some embodiments, the server may exchange data with the remote control device. The server may be configured to receive the locking instruction information transmitted by the user terminal. The locking instruction information may be input by the user when the lease of the UAV is about to expire or has expired, or when the user observes an abnormal condition in the UAV.

Step 102: based on the locking instruction information, transmitting a locking command to the remote control device of the UAV to enable the remote control device to lock the UAV based on the locking command.

In some embodiments, after receiving the locking command transmitted by the server, if the UAV is already landed on the ground, the remote control device may directly lock the UAV. If the UAV is in the air, the remote control device may lock the UAV after the UAV has landed.

In some embodiments, locking the UAV means that the operator can no longer control the UAV to fly. In some embodiments, after the remote control device locks the UAV based on the locking command, if the remote control device receives an operating command input by the operator for controlling the UAV, the remote control device may abandon the operating command (e.g., by not executing the operating command). In some embodiments, the remote control device may display a message to the operator indicating that the UAV has been locked, to remind the operator that the UAV has been locked by the user and the remote control device cannot execute any operating command input by the operator.

In some embodiments, the user may lock the UAV based on actual needs or based on the status of the UAV.

In some embodiments, prior to receiving the locking instruction information transmitted by the user terminal for locking the UAV in step 101, the method may also include:

obtaining task performing information uploaded by the UAV in real time while performing the task; transmitting the task performing information to the user terminal, such that the user terminal may provide the task performing information to the user. As such, the user may input the locking instruction information when observing an anomaly in the task performing information.

In some embodiments, the task performing information may include at least one of: a flight location, a flight velocity, a flight height, or an aerial photographing image. In some embodiments, the task performing information may also include sensor information acquired by sensors embedded in the UAV, such as the temperature information, humidity information, air pressure information, wind direction and wind power information, etc.

In some embodiments, while performing a task, the UAV may transmit the task performing information to the remote control device in real time. The remote control device may transmit the task performing information to the server. In some embodiments, the UAV may directly transmit the task performing information to the server.

In some embodiments, the server may transmit the task performing information to the user terminal after receiving the task performing information. The user terminal may provide the task performing information to the user. Various methods may be used to provide the task performing information to the user, such as through texts, images, voices or audios, and videos, etc.

In some embodiments, when the user notices an anomaly in the task performing information, the user may input the locking instruction information. The anomaly in the task performing information may include at least one of the following: a deviation of the flight path of the UAV from a specified flight path, the flight speed or height of the UAV has exceeded one or more predetermined values, or the images captures by the UAV do not match images of the predetermined working region.

In some embodiments, after the user inputs the locking instruction information, the user terminal may transmit the locking instruction information to the server. The server may transmit a locking command to the remote control device based on step 102 to instruct the remote control device to lock the UAV.

In some embodiments, when the UAV uploads task performing information in real time while performing the task, the user can input the locking instruction information when observing an anomaly in the task performing information, such that the UAV may be locked. This enables the user to handle various emergency situations, thereby improving the UAV control efficiency.

In some embodiments, the locking instruction information may include a scheduled locking time. Correspondingly, step 102 (i.e., based on the locking instruction information, transmitting a locking command to the remote control device of the UAV) may include:

based on the locking instruction information, at the scheduled locking time, transmitting the locking command to the remote control device of the UAV, such that the remote control device locks the UAV at or right after the scheduled locking time.

In some embodiments, when the user transmits the locking instruction information, the user may include a scheduled locking time, such as 20:00 on Nov. 21, 2016. After receiving the locking instruction information, the server may transmit the locking command to the remote control device at 20:00 on Nov. 21, 2016 to lock the UAV. In some embodiments, the scheduled locking time may be 2 hours after the server receives the locking instruction information. Then, 2 hours after the server receives the locking instruction information, the server may transmit the locking command to the remote control device to lock the UAV.

In some embodiments, by setting the scheduled locking time, the server may automatically transmit the locking command to the remote control device to lock the UAV at or right after the scheduled time, thereby saving time for the user and providing convenience to the user.

In some embodiments, the locking instruction information may include: an authorized flight mileage. Correspondingly, step 102 (i.e., based on the locking instruction information, transmitting a locking command to the remote control device of the UAV) may include:

obtaining a total flight mileage travelled by the UAV after the use of the UAV is authorized; when the total flight mileage of the UAV reaches the authorized flight mileage (e.g., when the total flight mileage is greater than or equal to the authorized flight mileage), transmitting the locking command to the remote control device.

In some embodiments, the server may obtain the total flight mileage after the use of the UAV is authorized directly from the UAV. Alternatively, the UAV may transmit the total flight mileage to the remote control device, and the remote control device may transmit the total flight mileage to the server.

In some embodiments, the UAV or the remote control device may transmit the total flight mileage to the server. In some embodiments, the UAV may transmit the flight velocity to the server in real time. The server may calculate the total flight mileage based on the flight velocity and a corresponding flight time duration.

In some embodiments, after the user authorizes a lessee to use the UAV, the user may transmit the locking instruction information to the server. The locking instruction information may indicate that the authorized flight mileage for the lessee to use the UAV is, e.g., 1000 km. Then, after the total flight mileage travelled by the UAV after the use of the UAV is authorized reaches 1000 km, the server may transmit the locking command to the remote control device of the UAV to lock the UAV.

In some embodiments, the locking instruction information may include an authorized flight time. Correspondingly, step 102 (i.e., based on the locking instruction information, transmitting a locking command to the remote control device of the UAV) may include:

obtaining a total flight time of the UAV after the use of the UAV is authorized; when the total flight time reaches the authorized flight time (e.g., when the total flight time is greater than or equal to the authorized flight time), transmitting the locking command to the remote control device.

In some embodiments, similar to the situation with the authorized flight mileage, the user may transmit the locking instruction information to the server after the user authorizes the lessee to use the UAV. The locking instruction information may indicate that the lessee is authorized to be use the UAV for a total flight time of 1000 hours. Then, after the post-authorization total flight time of the UAV reaches 1000 hours, the server may transmit the locking command to the remote control device to lock the UAV.

In some embodiments, by setting the authorized flight mileage and/or the authorized flight time, the server may automatically instruct the remote control device to lock the UAV when the post-authorization total flight mileage and/or the total flight time of the UAV reaches the authorized flight mileage and/or the authorized flight time. The user does not need to monitor the flight status of the UAV in real time. Therefore, the lease management efficiency is improved.

According to the method for controlling a UAV of the present disclosure, locking instruction information may be received from the user terminal for locking the UAV. Based on the locking instruction information, a locking command may be transmitted to the remote control device of the UAV, such that the remote control device may lock the UAV based on the locking command. The disclosed method provides timely control of the UAV to lock the UAV when lease expires or when the operator of the UAV conducts unreasonable behavior. The disclosed method can avoid continued operation of the UAV by the lessee or the operator, thereby realizing flexible control of the UAV, and providing convenience to the user.

The present disclosure also provides another method for controlling a UAV. This UAV control method may be based on the UAV control method described above in connection with FIG. 1, and may have additional features, such as an unlocking function.

FIG. 3 is a flow chart illustrating a method for controlling a UAV. The method of FIG. 3 may include:

Step 201: receiving locking instruction information transmitted from a user terminal for locking the UAV.

Step 202: based on the locking information, transmitting a locking command to a remote control device of the UAV to enable the remote control device to lock the UAV based on the locking command.

The entity for executing the method of FIG. 3 may be the server. Detailed implementations of step 201 and step 202 may be similar to those described above in connection with steps 101 and 102.

Step 203: transmitting an unlocking command to the remote control device to enable the remote control device to unlock the UAV.

In some embodiments, after the UAV is unlocked, the operator may continue to control the UAV to continue performing tasks. In some embodiments, after unlocking the UAV based on the unlocking command, when receiving an operation command input by the operator for controlling the UAV, the remote control device may control the UAV to perform actions based on the operation command.

In some embodiments, after the remote control device receives the unlocking command from the server, the remote control device may display a message to the operator indicating that the UAV has been unlocked, and that the remote control device can execute the operation command from the operator as usual.

In some embodiments, the user may unlock the UAV based on actual needs, or may pre-set a time for unlocking the UAV.

In some embodiments, before step 203 (i.e., transmitting the unlocking command to the remote control device), the method may also include: receiving unlocking instruction information transmitted from the user terminal; generating the unlocking command based on the unlocking instruction information.

In some embodiments, the user may perform operations to unlock the UAV based on actual needs. For example, the user may unlock the UAV when the lease is renewed by the lessee, or when the user replaced the operator of the UAV.

In some embodiments, when the user needs to unlock an already locked UAV, the user may directly input the unlocking instruction information at the user terminal. The user terminal may transmit the unlocking instruction information to the server to enable the server to instruct the remote control device to unlock the UAV based on the unlocking instruction information.

The disclosed method is simple, straightforward, and convenient for the user to flexibly unlock the UAV.

In some embodiments, the locking instruction information may include: a predetermined locked time period or scheduled unlocking time. Correspondingly, step 203 (i.e., transmitting an unlocking command to the remote control device) may include: when the time period in which the UAV is locked is longer than or equal to the predetermined locked time period, or when the scheduled unlocking time arrives, transmitting the unlocking command to the remote control device.

In some embodiments, the locking instruction information transmitted by the user terminal in step 201 may include a predetermined locked time period, such as 24 hours. After the server instructs the remote control device to lock the UAV based on the locking instruction information, and after the time period in which the UAV is locked is longer than or equal to the predetermined locked time period, e.g., after the UAV has been locked for 24 hours, the server may transmit the unlocking command to the remote control device to unlock the UAV.

In some embodiments, the locking instruction information may include a scheduled unlocking time, such as 20:00 on Nov. 22, 2016. After the server instructs the remote control device to lock the UAV based on the locking instruction information, when the scheduled unlocking time arrives, i.e., at 20:00 on Nov. 22, 2016, the server may transmit the unlocking command to the remote control device to unlock the UAV.

The disclosed method makes it convenient for the user to pre-set the time to unlock the UAV, such that when the pre-set time arrives, the server may automatically transmit the unlocking command to the remote control device. Thus, the disclosed method provides much convenience to the user.

In some embodiments, the disclosed method may also include:

receiving binding instruction information transmitted by the user terminal, the binding instruction information including information of the UAV and information of the operator bound with the UAV; based on the binding instruction information, transmitting a binding command to a corresponding remote control device, the binding command including the information of the operator, such that the remote control device only permits the operator bound with the UAV to log in or operate the UAV.

In some embodiments, the information of the UAV may include the name of the UAV, the identification of the UAV, the terminal serial number of the UAV. The information of the operator may include the name of the operator, the identification number of the operator, the employee number, the account number, etc. The user may bind the UAV with the operator to allow only the bound operator to operate the UAV.

In some embodiments, the user may input the binding instruction information at the user terminal. After receiving the binding instruction information, the server may transmit a binding command to a corresponding remote control device based on the binding instruction information. The binding command may include the information of the operator bound with the UAV.

In some embodiments, after the remote control device receives the binding command, the remote control device may store the information of the operator bound with the UAV. Thereafter, when an operator inputs log-in information at the remote control device, the remote control device may determine the information of the operator based on the log-in information. If the information of the operator corresponding to the log-in information does not belong to the information of the operator bound with the UAV, the remote control device does not allow the operator to log in or operate the UAV.

In some embodiments, the log-in information may include a user name and a password. The remote control device may determine information of the corresponding operator based on the user name of the log-in information.

In some embodiments, the information of the operator may be verified by the server. For example, after receiving the binding instruction information from the user terminal, the server may store the binding relationship between the information of the UAV and the corresponding information of the operator. When an operator inputs the log-in information at the remote control device, the remote control device may transmit the log-in information and the information of the UAV to the server. The server may determine whether the information of the operator corresponding to the log-in information has been bound with the information of the UAV. If the information of the operator corresponding to the log-in information has been bound with the information of the UAV, the server may transmit a message to the remote control device indicating that the verification is successful, such that the remote control device may allow the operator to log in or operate the UAV. If the information of the operator corresponding to the log-in information has not been bound with the information of the UAV, the server may transmit a message to the remote control device indicating that the verification is not successful, such that the remote control device may disallow the operator to log in or operate the UAV.

In some embodiments, through binding the information of the operator and the information of the UAV, the disclosed method enables the user to allow only specified operator to log in or operate the UAV, thereby improving the safety of the UAV.

In some embodiments, the method of FIG. 3 may also include:

after the UAV completes a task, determining a task performing quality level for the UAV based on a coincidence level between a predetermined specification of the task and actual performance of the task; transmitting the task performing quality level to the user terminal, such that the user terminal may provide the task performing quality level to the user.

In some embodiments, the predetermined specification of the task may include at least one of: a flight path, a flight height, a task performing time, or an amount of the task, etc.

In some embodiments, the user may pre-set the specification for a task. In some embodiments, the server may set the specification for a task based on a user's requirement on the task performing and based on actual condition of the task performing region. For example, the specification of a task may include: fly straight from point A to point B, with a distance of 10 km.

In some embodiments, after the UAV completes a task, the server may determine the task performing quality level for the UAV based on a coincidence level between the predetermined specification of the task and the actual performance of the task. For example, when performing a task from point A to point B, the UAV may fly along a straight line for the first 5 km, and may deviate from the predetermined flight path for the last 5 km. Then the coincidence level is 50%.

In some embodiments, based on the coincidence level, the server may determine the task performing quality level of the present task. In some embodiments, the task performing quality level may include two levels, such as pass or fail. In some embodiments, the task performing quality level may be divided into more than two levels, such as excellent, good, pass, and fail. The task performing quality level may be transmitted to the user terminal, such that the user terminal may provide the task performing quality level to the user. The user may be the owner of the UAV, or may be a trustor who entrusts the individual owner or corporate owner of the UAV to perform tasks.

In some embodiments, the user may assess the operator based on the task performing quality level. In some embodiments, the user may process the payment of a fee associated with the task performing. The server may automatically calculate the fee associated with the task performing based on the task performing quality level and predetermined rules for calculating the fees, and may provide the calculated fee to the user.

According to the disclosed method, after the UAV completes a task, the task performing quality level may be determined based on the coincidence level between the predetermined specification of the task and the actual performance of the task. By the disclosed method, whether the task performing satisfies a predetermined quality requirement can be determined in time, thereby improving the efficiency of processing fee payment related to the task performing conducted by the UAV and the efficiency of assessing the operator.

In some embodiments, the disclosed method may also include:

receiving crop information of at least one region input by the user, or determining the crop information of at least one region based on photographing information or sensing information acquired by the UAV; performing a statistical analysis on the crop information and storing the crop information.

In some embodiments, the user may input the crop information of at least one region through the user terminal. The user terminal may transmit the crop information to the server. In some embodiments, the server may obtain the photographing information or sensing information acquired by the UAV from the remote control device, and determine the crop information of the corresponding region.

In some embodiments, after determining crop information of multiple regions, the server may perform a statistic analysis on the crop information for each of the regions. The server may obtain the distribution of the crops in each state, city, county, village, or over the entire country or the world. Such distribution information may provide technical support for future development in agriculture, forest, fishing, or farming.

In some embodiments, the crop information may include crop types and starting dates over the past years when UAV-executed tasks were first performed for the crop types, respectively. Correspondingly, the disclosed method may also include: based on the crop information, within a predetermined time period before the starting dates, providing reminding messages to users who grow one or more crop types.

In some embodiments, based on a user input or information obtained by the UAV, the server may determine that in a certain region, weeding and spraying of pesticides for crop A are typically performed in April, then within a predetermined time period before April, the server may transmit reminding messages to users who grow crop A, to remind the users to perform tasks such as weeding or spraying pesticides. A user may be the owner of the UAV, or may be a trustor who entrusts the individual owner or corporate owner of the UAV to perform tasks. The predetermined time period may be set by the user, or may be a default time period, such as 7 days.

In some embodiments, the crop information may include a growing area for the crop and information indicating whether the crop suffered from attacks by diseases or insects. Correspondingly, the disclosed method may include: based on the crop information, calculating a proportion of an area in which the crop suffered from attacks by diseases or insects over the total growing area of the crop; if the proportion is greater than a predetermined value, providing an alert message to the user.

In some embodiments, the proportion may be determined based on the area of the crop that suffered from attacks by diseases or insects and the total growing area for the crop. If the proportion is greater than the predetermined value, it may indicate that the disaster is serious. The server may provide alert messages to the user who grow the particular type of crop or all of the users, to remind the user(s) to take a note and process the affected crop. The predetermined value may be set by the user, or may be a default value set based on actual needs, such as 30%.

In some embodiments, the disclosed method may also include:

receiving activation request information transmitted by the remote control device, the activation request information including personal information of the user who requests to activate the UAV; based on the personal information, determining whether to allow the user to activate the UAV; if it is determined to allow the user to activate the UAV, transmitting an activation instruction to the remote control device to instruct or enable the remote control device to activate the UAV based on the activation instruction.

In some embodiments, the seller of the UAV or the owner of the UAV may provide personal information that may be used to activate the UAV, including, for example, name, telephone number, identification number, account number, etc. When the UAV needs to be activated, a user may first log into the remote control device, and then input the personal information. The remote control device may transmit activation request information to the server. The activation request information may include the personal information of the user who requests to activate the UAV.

In some embodiments, the server may determine whether to allow the user to activate the UAV based on the personal information. If the server determines to allow the user to activate the UAV, the server may transmit an activation instruction to the remote control device to enable the remote control device to activate the UAV based on the activation instruction. In some embodiments, only after the activation, the user is allowed to operate the UAV through the remote control device.

In some embodiments, if the personal information included in the activation request information is inconsistent with the personal information previously received by the server that would permit the activation of the UAV, or if the server has not yet received the personal information from the user terminal that would permit the activation of the UAV, then the server may transmit an activation failure message to the remote control device. The remote control device may provide the activation failure message to the user who requests to activate the UAV.

In some embodiments, by setting the activation process, the disclosed method allows activation of a UAV only by a user whose personal information has been registered at the server. This further enhances the safety of the UAV, and facilitates the management of the UAV.

In some embodiments, the disclosed method may include: transmitting a no-fly command to the remote control device, the no-fly command including a no-fly region and/or a no-fly time (e.g., at least one of a no-fly region or a no-fly time).

In some embodiments, the no-fly command may be set by the user. For example, the user may transmit the no-fly region and no-fly time related to the UAV the user owns to the server through the user terminal. In some embodiments, the no-fly command may be set by the server. For example, a certain region or a certain time may pose danger to the UAV or due to certain political reasons, the UAV cannot fly in a certain region or at a certain time.

In some embodiments, after the remote control device receives the no-fly command transmitted by the server, based on the no-fly command, the remote control device may ban the UAV from flying in the no-fly region and/or at the no-fly time.

In some embodiments, after the server transmits the no-fly command to the remote control device, the disclosed method may also include:

The above described processes can be applied to the situation where the user sets a no-fly region and/or a no-fly time for the UAV. After the flight is banned for the UAV, the remote control device may receive ban-lifting request information input by the operator, and may transmit the ban-lifting request information to the server.

In some embodiments, the server may provide the ban-lifting request information to the user. When the user determines to lift the ban on flight, the user may input the ban-lifting instruction information through the user terminal. The user terminal may transmit the ban-lifting instruction information to the server. Based on the ban-lifting instruction information, the server may transmit a ban-lifting command to the remote control device. After receiving the ban-lifting command transmitted by the server, the remote control device may control the UAV to lift the ban on flight based on the ban-lifting command.

In the present disclosure, by setting the no-fly region and/or the no-fly time, the flight safety of the UAV is improved. After the flight of the UAV is banned, the operator may send ban-lifting request information through the remote control device, to request the user to lift the ban. The disclosed method makes it convenient for the user to manage the operator and the UAV.

According to the disclosed method for controlling the UAV, an unlocking command may be transmitted to the remote control device to enable the remote control device to unlock the UAV in time, thereby improving the flexibility in controlling the UAV.

After the task is completed, the user may determine a task performing result based on the actual task performing status, and may calculate the cost, price, etc., associated with the task.

9. Leasing Service

Industry application UAVs, such as agriculture UAVs, typically do not adopt a business mode in which individual farmers purchase their own UAVs. Instead, the business model is to lease UAVs from corporates who own the UAVs by organizations formed by farmers. In other words, a corporate may purchase a number of UAVs. While the corporate may use a portion of the UAVs in its industrial applications, the corporate may lease out unused UAVs, or may run a business of leasing and maintaining the UAVs. The lease may be determined based on flight mileage, flight time, or lease time.

In some embodiments, the lease procedure may include: first, the user determines a method of collecting the lease fee, which is typically calculated based on the acreage of the field. Then, the user may set the control right and the team forming right for the lessee on the user management platform website. After the lease starts, the server may release corresponding functions to the lessee based on the control right and the team forming right. During the lease, the lessee may pay the lease fee based on the real time flight record. The user may set the lease expiration date on the user management platform website, such that the UAV may be locked after the lease expires, so the UAV cannot take off.
